The present research included synthesis of silver nanoparticle from(1*10 -3 ,1*10 -4 and1*10 -5 ) M aqueous AgNO3 solution through the extract of M.parviflora reducing agent. In the process of synthesizing silver nanoparticles we detected a rapid reduction of silver ions leading to the formation of stable crystalline silver nanoparticles in the solution. The characteristics of silver nanoparticles were studied by using UV-Visible absorption spectroscopy, and atomic force microscope (AFM) analysis. The AFM measurements showed that the average size of silver nanoparticles synthesized using (1*10 -3 ,1*10 -4 and1*10 -5 ) M aqueous AgNO3 solution through the extract of M.parviflora were 102 to 114nm. UV-Vis spectra of the aqueous medium containing silver nanoparticles showed a surface peak at 220nm and 445nm for (1*10 -3 ,1*10 -4 and1*10 -5 ) M aqueous AgNO3 solution through the extract of M.parviflora. The study of nanoparticles due to the possible application for the development of new technologies such as exhibited inhibitory effects on Ecto-5'Nucleotidase (5'-NT), ADA and AMPDA enzymes in Sera of control and Patients with Arthrosclerosis. Further studies on other biological activities are required to exploit their full potential.
